My Sony Xperia J: Maximize the Capacities and Fixing the Problems

Hey Guys, have you tried to buy a new Smartphone of Sony Xperia? If not yet, don’t buy… just kidding! Yeah I got one and it is my first time, basically through its appealing design I was convinced to buy one of them. But it is awful when I didn’t read the user review before buying this latest Sony Xperia J. And I had encountered lot of problems using this phone after one month usage. So I came up with this sort of adaptation, wherein I tried to expand its capacities and I looked for any applicable solutions. Photo Source: http://www.sonymobile.com/global-en/products/phones/xperia-j/ So here’s the summary of some of the Tech Blogger comment/review on Sony Xperia J:

GOOD

BAD

Appealing design

Sluggish performance

Decent screen

Poor camera

Decent price

Not much internal storage

From here I would like to discuss my solutions and eliminate the feeling of guilt. When you already bought this unit and experience the problem, please try to read it. We will tackle the problem one by one and from there I would give my solutions afterwards.

Sluggish Performance

PROBLEM: it does not quickly respond when you try to slide it or type on the keypad, it is frustrating. One thing you can do is to turn it off and then power on again, but for few minutes it will same happen again. SOLUTION: Follow the steps to help you from slow response of your phone touch screen.

Unzip or extract the file TouchFWToolsAP_Sony-Ericsson-JDM-Platform-Signing-Live-54f9-3.apk

Copy it to your SD card then put check to the Unknown sources (go to Settings>Security> Unknown Sources then mark by check) after installing the files please unmark Unknown sources box again.

Install this on your mobile.

Put your mobile in a plain surface and click the button “calibrate”

Application function: This is a so-called “calibrator”, but it makes no calibration at all, it just patches the phone. For those that are not familiar with this million-users defect, this patch / fix will work for sony xperia phones with the laggy touch screen. (Excerpt from-http://talk.sonymobile.com/thread/57749?start=0&tstart=0)

Poor Camera

PROBLEM: It has only 5.0 megapixels. SOLUTION: Maximize the photo enhancement feature of the phone; just download an application from Google Play that suits to your need. I will recommend Pics-art application for its nice editing features. RECOMMENDATIONS:

Install Antivirus like AVG to avoid glitches and to secure when downloading applications to your phone which might also optimizes phone operation.

USB Reverse Tethering With the use of USB Reverse tethering you can surf on your mobile (using the internet connection on your PC) through the USB tunnel.apk (Available in Google Play Store). While USB tethering uses the smartphone’s internet connection for your desktop, reverse tethering does the complete opposite. It will give a very high internet speed compared to the 2G connection and will also save valuable data of your 2G plan. Downloading and updating apps from the Play Store is also possible. For this you just have to enable your mobile data. If you disable the mobile data reverse tethering will work but you won’t be able to use the Play Store. Here is the tutorial for USB reverse tethering (Definitions & Procedure from http://www.themobimag.com/reverse-tethering-using-usb-tunnel/). Requirements: 1. A rooted android phone. 2. USB tunnel app. 3. Desktop files needed for reverse tether. Steps:

Download the USB tunnel apk.

Place the apk on your sdcard and install it using any file manager.

Download the files for your desktop.

Now connect your Android to your desktop via USB cable. Do not turn on USB storage.

Dear Andrew,
I think it really works for my xperia j. After downloading it and install, I use it to calibrate then after few days application logo will disappear. But the patch still installed so no problem. I already update my software to Jelly Bean 4.1.2 but the patch still works. You should try it!

I think xperia j is also okay with jelly bean. It has new format for its setting but it does not really change a lot. I like its baterry setting because it has option that optimizes the battery life. My only problem is how to root it? Unlockroot free doesn’t work for jelly bean. So now i’m trying to find out how. Anyways, Hope i was able to help you. Good day!

Actually I purchased a week ago and was working fine till yesterday. However the moment when I restarted the phone today, there is a huge delay/lag in typing (it does not respond to the key press and taking too much time to show up the text) and also lag while unlocking the screen (almost I need to try for 4 to 5 times to unlock the screen). Basically it has become too slow..

Since you are talking mainly on unlock Slide issue..whether this patch will correct the typing lag also??

Absolutely worked for me! Just install it but first mark the UNKNOWN SOURCES option in ur setting. Then calibrate ur phone just follow the direction cited. Please give me feedback after doing it. Thank you very much.

I tried installing the app but when I run it it gives an error saying that the app has stopped working. My phone is in Jelly Bean already. Just bought my phone a month ago. My phone right now is completely useless. :(

Sorry to hear that, yeah I actually installed first the calibration tool before updating it with Jelly Bean. Have you tried to reset to its Factory setting? If yes you could try it again to re-install the calibration tool from my link follow all the direction cited. (If it doesn’t work you should ask assistance in any SONY service provider because your warranty still valid.) My Idea is that the phone does not updated correctly. So Please give me feedback after resetting your phone (BACK UP ALL YOUR FILES) and installing the APK from my link. Thanks.

I just reset my phone into factory setting. All data was erased, but the firmware and android version are still the same (latest; i.e. latest build and still jelly bean).. and more, I still got the error. :(

After I upgraded my xperia j to version 4.1.1(jellly bean), its earphones are not working and when I restarted its ear phone worked but head phone is not working. I contacted xperia care & they told me to reset my phone or repair the software. I reset the phone but its of no use. No error has been rectified and I am not finding the repair option. Plz help me & suggest me what to do

Will the calibrate.apk will work for the Andriod Build version number 11.0.A.75 (ICS)?? I just bought this phone a week ago and having the slide unlock phone issue and sometimes i can’t even receive the calls.

Chito,
I successfully installed the calibrator.apk and it worked fine. But still sometime the slide unlock issue is not responding. The issue is not that frequent, earlier it was like 4-5 times a day but after calibration its happening only once a day. Please assist.

Okay, I somehow managed to downgrade to 11.0.A.3.28 (ICS) and got the calibrator.apk working. Seems fine. It’s just like the first time I laid my hands on this phone. Though I am still observing it, cause I have read that other Xperia J users returned to a laggy screen after a while. I am now updating it to 11.0.A.7.5 and I will stay there for a while before I will move on to JB.

So for those who encountered same problem as me, and want to downgrade their firmwares, follow this tutorial:

Steps:
1.) If you are already in Jelly Bean (JB), the Calibrator.apk won’t probably work. In this case you have to downgrade it to Ice Cream Sandwich (ICS) (11.0.A.3.28) or to 11.0.A.7.5 (I haven’t tried downgrading to this one, though I think it will just be the same process and success rate). Don’t worry of bricking your phone since it will work 100% for as long as you follow the instructions given in the tutorial link above.

2.) After the downgrade, install the calibrator.apk found in this blog, you can use a file manager such as Astro or you can install it directly from your PC using Wondershare MobileGo software (this is the one I used), make sure that USB Debugging Mode is enabled (Settings->Developer Options->USB Debugging Mode). After installing the app, open it (in your phone), and click the Calibrator button. Wait for it to finish (it will take just about 10sec).

3.) Voila! Feel the difference! :)

4.) Optional. You can upgrade your firmware to later versions. In case of Chito, the author of this blog, he upgraded to Jelly Bean without the screen problem anymore. I’ll go back to you guys what will I found out after a month, if the touch screen issue returned.

So to all Sony Xperia J users just take a time to read my blog and give me your comments or questions, I will also take my time to answer them. Don’t forget to Like this page. Thank you very much. CHEERS! :)

Hey there… I got this phone (XperiaJ) 2 days back and from 2nd day onwards got this touch issue… So without taking any chance i installed and calibrated using this app… I think the problem is solved for now… :):)

One question: when i got this issue for the first time, i tried to switch off my phone, but was unable to switch off (as it required the touch input and my touchscreen was unresponsive). Even long pressing power/unlock button didn’t work..
Is “battery removing” the only way to switch off the phone ?? when its touch screen is unresponsive ?? Please help…

I think it also works with jelly bean.
When my phone was restored due to hardware malfunction. I’m already updated with jelly bean so i tried to install the patch but there’s no problem encountered and perfectly fine. You should try it too with your jelly bean xperia j.
Hope this helps you.:)

Btw i still haven’t bought the phone,but i’m thinking of bying it next week,because for the money i have it’s kinda the best phone in my country.Should i buy it? Because i don’t have more money for another phone and this is the only good phone in this price range here.What do you say? Some people say it’s good,some say it’s not good.There’s alot people complaining about lag but i’m hoping that can be fixed.Small lag shouldn’t be a problem.I’m really hoping that you’ll give me an opinion on this phone.What are the pros and cons in your opinion? Thanks.Looking forward to your answer!

Hi
The problem I am having with my Sony Xperia J is that it is overheating so much that IU have burnt myself on it a couple of times! The bit which gets scorching hot is the metal bit where the memory cards and sim cards go. I bought a new battery but same problem. Three days ago I replaced the phone itself for another Xperia J and that is still as hot! Even if I send one text message the thing can burn my fingers. What is going on? Have I done anything wrong or is this a common fault in this phone? The thing is at the shop they said they had not encountered this before but how come it has happened to me with two completely different phones and batteries? Please can you help? Thanks.

Hi
Just read a couple more accounts on internet of people having the same problem with the Xperia J. So it’s not just me. I think one suggestion was to run battery down completely until it’s totally dead and then charge battery/phone back up to ful capacity? Does this sound like a possible solution?

Was wondering if phone is overheating because I have it on charge nearly all the time because the battery runs down so quickly? For example if I leave it overnight not on charge it is completely dead by morning. So I tend to leave it charging. Do you think this may have charged the battery so much over a period of months that it overheats the phone when I use it? Thanks. Look forward to hearing your ideas.

Your phone problem is kinda new to me. This could be manufacturing malfunction or battery defect. It is advisable to replace it with another phone or battery. Btw, in charging my xperia j I don’t let the battery drained, someone from sony center advice me that if you see the battery low sign charge it immediately. And then remove the charger when it already reached the 100% charge.

Ok Chito. Thanks so much for your advice. It just seems really strange that I have had two different Xperia J’s and two different batteries now and both have become really hot after minimal use and the battery drains from completely full to completely empty within about three hours even when I have not even used the phone for a text message. Maybe I had a faulty battery to start with, then I got another off ebay. And the reason the second one was on ebay was because the seller had realised that one was faulty too?

Kind regards

Chris

PS Any idea how much for a brand new battery and where would I get one from? I am on a contract with orange.

Hi i’m having problems with spotify (and some other apps) that are not able to connect to facebook. Before using the app for the first time, you have to connect to facebook, so it goes to the website but the page won’t load, it keeps blank no matter how many times I keep refreshing it. But I can log on perfectly on FB, it’s just de connection between the apps and facebook that’s not working. This is for all the apps that r trying to make a connection through Facebook. Is it bcz I turned my synch off or something like that?

The good thing in using this calibrator.apk is that you just like trying to install an application from app store. Believe me it will not cause void in your warranty because i have tried already when my earphone didnt work the service center did not question anything about it and just replace the broken earphone. The calibrator.apk is the most amazing solution for xperia j sluggishness!
Have a nice day.

Thanks Chito I shall try installing it and see how it works. Meanwhile I switched the ‘Touch and Hold delay’ option under Accessibility to ‘short ‘and it seems to have solved the touch screen issue to minimal.

Hi. I am having a lot of issues with my xperia j (which was a gift from my kids on Jan.2013) since May 2013. I have that sliding issue every now and then; but it isn’t a major thing. I also have the same issue as Chris’. My phone gets really hot! But I usually charge my battery when it is at 20% or less (but not completely drained), so I was really wondering why it gets so hot. And battery life is short as well. Somebody told me it’s because I have so many apps running even when I’m not using. Is that true? I removed most of the game apps already and still battery consumption is fast.
My main issue is storage. My phone only has 2gb internal storage and 775 mb phone memory (as opposed to what i saw on the sony page wherein xperia j has 4gb). I have a 32gb micro sd. but of course, most apps wont save on the external sdcard. So, I want to know how I could maximise my micro sd. My daughter bought it so I could have space for my favourite apps. I don’t have that sony adapter that sony recommends.Have you partitioned your micro sd? if so, how is it working for you?

Hello, i think your problem in battery is the same with chris. Yes its true when using apps and also if your connected with wifi or any data connection while charging phone will cause excessive heat from the back near camera lens. Just try not to use your phone while charging. And also about the maximizing the ext sd card, i think one of the disadvantage of xperia j is that it couldn’t save apps in sdcard and applicable only in phone memory and internal storage. I haven’t tried to partition sdcard though sorry i couldnt help you with that. Have a nice day!

Hey there!
I got my Xperia J in Nov 2012. I had problems with the touch screen but then I upgraded it to jelly bean and those problems vanished, Literally! Even if the touch problems persisted I used to restart the phone and then it touch used to work fine. But then there was another software update 11.2.A.0.31 and so I decided to go for it, but I stopped the upgrade mid-way and after that the touch screen of my phone started responding horribly! I decided to upgrade again, once it was done the screen showed no changes! I decided to settings reset my phone but it still has the same problem. What do I have to do to get its perfectly functioning touch screen back?

Hi guys am using dz phone for last 5 months i got calibration issue nd i installed dz software it was good but now again am facing the same peroblem even after calibrating many times is any other solution is thr for issue plz inform me frndz…

This is one of the worst phones i have ever used..Such a piece of crap…screen never responds in time,playlists and videos gets hanged all the time..Camera takes too much of time to start as well as to save a picture..The processor is not capable of performing the functions as per the specifications..Notification lights do not function, very slow in responding to any of the commands. A China made phone can function superiorly than this one and moreover its cheap too…Investing in this SONY XPERIA J is just a waste…..

Dear chitotech,
I have purchased this fucking piece of shit (sony xperia j) and facing the touchscreen issue from day1. Even I have tried calibrate.apk, because of which touch screen issue got minimized but still iam facing the issue.

I have some other issues with the phone,
When I try to listen to my walkman and browse on the internet, music player stops in middle and jumps to some random song or to the first song in walkman. I have written to sony they have asked me to clear cache of walkman. But the issue is not fixed.
2)Another issue is if I transfer any songs via bluetooth and if any images are present in bluetooth folder album art of the song changes to images in folder. Tried updating album art Cannot update album art by downloading music info.
3)When I play videos they stop suddenly with an error message cannot play video. These videos are supported and played earlier.
4)i am not even updating the apps on my phone because the free ram is 80 mb even after stopping the background apps
Hope u have solutions for these and sorry for annoying post.
Awaiting for your reply
Thanks and regards

Hi, when the phone shuts down because of the battery, it looses all the contacts. It happened to me twice. I tried to import contacts from the SIM card as well as from the memory but it says that there are no contacts to import. It’s the worst phone ever :(

Hey, the front facing camera on the Xperia J is very poor quality. Even when the room is lit the picture is dark. Unless you’re in a very brightly lit room the camera takes a blacked out photo. Other people with this phone are also having the same problem. Any way to solve this without having to be in a bright room while taking the photo? Thanks

Hi there, don’t use your phone while charging because it will heat up especially at the back of your phone. Shut down all the open apps through long press at the Home button and then swipe it out. In my experience, the phone heats up while using it for calling when the data connection is activated. So deactivate the data connection and/or wifi connection while calling. Try this, hope it will help you.

Nope,it would not be a problem. In my case I have tried it once when I rushed into a Sony service center and my phone got earphone issue. The center didn’t ask for the calibrate.apk and my phone got resolved without questioning the warranty. But for a rooted phone, I haven’t tried yet…hope it answers your concerns. Thanks:-)

Hello,
Im just wondering if you can help me about my xperia j?
After rooting it all of my photos & music on sd card got deleted, and try to take pic. and save it but after a while my album shows “There is no item on your collection” (EMPTY)

Dear Scuda Fisher
Can you please test your speaker with this- dial your phone *#*#7378423#*#* then press Service test then SPEAKER. This is to check if there is a problem with your speaker hardware. With regards to “earphone”, just pick the options after dialing the number. If the Service tests didn’t work to your phone, it might have problem to its hardware component. Hope it helps you.

Good day!
I am planning to collect more good photos though my next blog is all about photography using my Sony Xperia J. Will update maybe some other time if I had completed the said photos. Moreover, you can see my sample photography using Sony Xperia J at http://www.flickr.com/chito_brown/ . Thank you for your support!
